What major theme is emphasized in the chorus's ode regarding the Labdacids family?

The major theme emphasized in the chorus's ode regarding the Labdacids family is that fate is inescapable. In "Antigone," the Labdacids, particularly Oedipus and his descendants, are depicted as being caught in a tragic cycle dictated by fate and prophecy. The chorus reflects on the inevitable consequences of their actions and the sorrowful legacy that follows them. This overarching theme illustrates the idea that no matter how much the characters strive for control or attempt to alter their destinies, they are ultimately powerless against the predetermined fates that the gods have laid out for them. The focus on fate reinforces the tragic elements of the story and highlights the belief in the limitations of human agency in the face of cosmic order.
